You can't upgrade from CentOS 5.6 to CentOS 6.0.
Rather you would need a fresh installation of CentOS 6 and migrate your data to new server.

It is possible but Red Hat (Centos is a mirror replica of Red Hat) does not recommend doing it.
See here
There are some people who have done it though.

The best idea is to backup your system and reinstall.
- Backup /etc completely.
- Run this command "chkconfig --list | grep :on" list all the active services.
- Transfer /etc backup to the new system and open it to another location.
- Install the new system then install all the packages required using the list.
- Replace the config files from the /etc backup
- Check the old system fore iptables rules adn SELinux if enabled adn apply same rules to the new system.
